I had one with buttons and it drove me NUTS..... I still have it and I would have given it to you if you wanted it... I only used it 1 day.... I like to turn down my volume quick if I have to.. and I can control alot more using that knob

Oh.. I also have a spare 98 Nissan Maxima CD player too that I was pimpin in my car the first 2 months I had it
